WRITING-PAPER TABLET.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed May 11,1906. Serial No. 316,256.

To (LZZ whom, it may concern:

Be it known that I, LYMAN H. NELSON, a

citizen of the United States of America, and

a resident of Portland, Maine, have invented certain new and usefulImprovements in Writing-Paper Tablets, of which the following is aspecification.

My invention relates to the manufacture of pads or tablets of writing orother paper, such as arecommonly sold in stationerystores, news-stands,&c. Such pads or writing-tablets are commonly made up of a plurality ofsheets assembled and formed into a block, one end of which is secured byglue or cement to. a cloth binder which overlaps the end of the blockand is secured on each side of the block to a cover composed of a singlecardboard-sheet. .The individual sheets being simply glued by one'end tothe binder are readily pulled out, as required. ..Writingpaper isprepared and sold in large quantities m such pads, and the upper coveris frequently decorated with some fancy design, giving the pad theappearance of an oblong book openmg at one end. This constructionanswers very well when the sheets are of thin flexible paper, or evenwhen thick paper is used if the atter is handled with great care and thesheets simply torn ofi one at a time beginning at the top; but when thesheets are opened up in the body of the pad or book or the plad isaccidently dropped or otherwise roug ly handled the edges of the sheets,which are glued to the binder, will immediately pull off and the bookwill fall to pieces.

The reason for this is that the paper bein heavy and not easily bent andbeing attache to the binder by the edge'only there is a leverage exertedat the edge tending to break it away when the sheet is bent. Many ofthese pads are now made with heavy paper, each sheet of which has asouvenir picture or desi and when these pads are exposed for sa e thepublic frequently open them u to examine them, and they mimediately fa lto pieces and are s oiled. This fault with the pads as now ma e is aserious one and practi-' cally prohibits the sale of souvenir writmpaper when the paper as any considerab e wel ht or body;

' T e object of my invention is to bind a plurality of -sheets ofwriting-paper having considerable body or thickness into a pad or book,securing the attached ends of the sheets to the binder so that they maybe readily detached to leave a clean edge and yet holding them stronglyenough so that the pad or book may be opened and manipulated to areasonable extent for the purpose of inspection without falling apart.

tablet containing a plurality of sheets of paper placedtogether to forma pad or block o1 removable sheets having a stepped constructionconstituting one beveled end with a continuous coating' of adhesivematerial on said beveled end which covers the end and one adjacent faceof each sheet and fills the angular recess between the ends, and inconnection with this construction I preferably use a binder of cloth orother flexible material. By this construction each sheet gets a coatingof glue not only onits extreme edge, but also for a short distance inon-the-under side adjacent to the edge, so that it is held in an angleofgluewhich adheres to the edge and under side. As a result, when. oneof the detach it is parallel with the cemented surface on its under sideinstead of pulling diattached by the glue. By forming the pad or book inthis way I do not add anything to the cost of construction. I get a padwhich is far stronger than the old construction and capable of beingopened'up and manipulated to considerable extent without coming apart. Iam thus enabled to put on the market heavy souvenir letter-paper withoutdanger of having the same spoiled by examination of would-be purchasers.

, I illustrate m invention by means of the accompanying rawings, inwhich- Figure 1 is a perspective view of a pad or book constructedaccording. to my invenbe formed the ends of the sheets are fanned orshingled, so that they overlap'r oflset forty-five degrees from theperpendicular.

tion. Fig. 2 is an enlarged section through The pad or block A is madeup of a plupaper which it is desired to orm into book each other fromthebottom upward, forminga beveled end to the pad, which slopes fromthebottom backward and u ward. I find in practice that the best res ts areattained by making the inclination or bevel about The inventionconsists, broadly, of a paper a sheets is bent upward the pull whichtends to rectly away, as it does when only the edge is To this beveledend is secured the cloth or other binder c in the usual way by the useof glue or other suitable cementing material, a thickness of cheesecloth0 being inserted between the binder proper and the glue, as here shown,although the binder may be glued directly onto the back of the sheets.As a result of this construction, it will be seen that the extreme endof each sheet and a short section (1 of the sheet adjacent to the underside, as shown in Fig. 2, will be found adhering to the binder c, andany tendency to bend one of the sheets upward will be resisted by theadhesion of the under surface, and the pull will be a pull in the lineof adhesion, as explained. A lower cover I) and an upper cover B areapplied in the usual way by bringing the edges of the binder 0 aroundthe corners and cementing them onto the covers.

In order to make the pad more stable and less liable to break away atthe top, I score the uppercover at 1) parallel with the back edge and.in front of the overlapping edge of the binder, so that when the coveris opened the joint will come at that point and not at the back edge.

It is evident that this method of binding may be used in binding books,pamphlets, &c., when heavy paper is used, and it is applicable to agreat variety of uses.

I claim 1. The herein-described paper tablet consisting of a pluralityof sheets of paper placed together to form a pad or block of removablesheets having a stepped construction constituting-one beveled end, acontinuous coating of adhesive material on said beveled end which coversthe ends and one adjacent face eaaeeo of each sheet and fills theangular recesses between the ends.

2. The lIOIGlll-(lUSClllMHl paper tablet consisting of a plurality ofsheets of paper placed together to form a pad or block of removablesheets having a stepped construction constituting one beveled end and abinder having a llat adhering surface secured on said beveled end byadhesive material which coats the end of the pad and adheres to the endand adjacent portion of the face of arch sheet and fills the angularspace between the sheets.

3. The l\erein-rlescribed paper tablet consisting of a plurality ofsheets of paper placed together to form a pad or block of removablesheets, the ends of the sheets at one end of the pad being arranged tooffset or overlap each other from the bottom to the top to form agenerally beveled end and a binder having a flat adhering surfacesecured to the generally beveled end of the pad by an adhesive'substancewhich coats the end of the pad and adheres to the end and to a portionof one adjacent face of each sheet and fills the angular spaces betweenthe sheets.

4. The ll(ltl1l(l(SClil)((l process of forming a pad or tablet ofremovable sheets which consists of assembling a plurality of sheets ofpaper to form a pad or block, fanning" or offsetting the sheets at oneend of the pad, coating the. end with adhesive material and finallyapplying a binder having a flat adhering surface to the offset end b-vnu lns of said adhesive material. f
